In Ese Ejja, an ergative Takanan language spoken in Peru and Bolivia, four subordinators with three allomorphs each mark referential congruence or incongruence vis-&#224;-vis their matrix clause. While same-subject/different-subject systems in subordinate clauses are well attested crosslinguistically, this language also makes further, less usual, distinctions. On the one hand, it displays two distinct tripartite systems rather than a (mere) binary one. On the other hand, these systems display alignment features that differ from the straightforward ergative alignment found in main clauses. Interestingly, highly elaborated switch reference systems including a similar subject-object coreferentiality have been reported for a number of Panoan languages with which the five Takanan languages are claimed to be related.
